Answer:
Step-by-step explanation:
Originally, the show featured ten tough “greaser” kids at Rydell High, all of whom have Polish and Italian surnames. The 50s era rock n roll score has a feature song for nearly every character. In general, the original book has rougher characters with much less hopeful lives, approaching life after graduation with modest dreams. You will recognize Sandy, Rizzo, and Danny from the 1978 film, and their characters’ interrelate in most of the same ways. But the movie added a few anodyne subplots, and there is more of an adult presence for all those interminable cameos by Sid Caesar, Eve Arden, etc.
Each iteration of Grease has moved further from rough punks at Rydell (standing in for Taft) High School. First, for the dinner theater crowd, the character with numerous bigoted observations is left out. Then, the movie comes along, and suddenly the roughest plot point is over deciding to drop out of school, and Danny letters in track, diluting his greaser bonafides. Most 21st Century productions would be more accurately described as adaptions from the movie, which once held the distinction of the top-selling movie soundtrack of all time.
The tough city kids have been suburbanized, sanitized, anglicized, and rendered more harmless with each adaptation.
